Data from the groundwater level
recorders at Golla and Kalyandurg
(see Figure 25) do not correlate well
with the findings of the Groundwater
Department’s survey in this mandal.
In the case of Golla, this can be explained
by the fact that the recorder is sited
in a locality with a relatively low level of
groundwater extraction. Also the actual
site of this recorder (as with many others)
was chosen primarily on the basis of the
security of the equipment. The wider
implication is that water-level recorder
information should be used with extreme
caution when assessing regional impacts
of, say, watershed development.

Box 9. Electricity tariffs for
irrigation wells
One-off connection charges
include: a Rs.25 application fee,
a Rs.100 security deposit and
a development fee of Rs.1,000
per HP of the pump. Once
connected, the electricity tariff
is an annual charge that
depends only on the rating of
the pump. Pumps with ratings
of up to 3 HP, 3-5 HP, 5-10 HP
and more than 10 HP have
annual tariffs of Rs.225,
Rs.375, Rs.475 and Rs.575
respectively. Farmers with small
and marginal holdings can opt
for unit payment or optional
tariff of Rs.0.2 per unit up
to 2,500 units and Rs.0.5 for
consumption in excess of
2,500 units.
